If you expect to owe at least $1,000 in federal tax after withholding and refundable credits, and your withholding is below the IRS safe-harbor percentages, you may need estimated payments. For most calendar-year individuals, the 2026 installments are due April 15, June 15, and September 15, 2026, and January 15, 2027. Use the 2026 Form 1040-ES worksheet to calculate the amount, then pay through IRS Direct Pay, an IRS Online Account, electronic funds withdrawal, a card or digital wallet processor, or by mail.
What quarterly estimated tax payments are
Federal income tax is a pay-as-you-go system. Employees usually pay during the year through payroll withholding. If you receive substantial income without enough withholding—such as self-employment income, freelance fees, rent, interest, dividends, capital gains, or retirement income—you may need to send the IRS estimated payments yourself.

Estimated tax can cover both expected income tax and self-employment tax. It is not a separate tax or a special account. Each payment is an advance credit toward the federal tax reported on your annual return.
This guide covers federal estimated tax for individuals for tax year 2026. State and local estimated-tax requirements are separate and may use different thresholds, forms, and dates.

Do I have to pay estimated taxes?
The general IRS test has two parts. You generally may need estimated payments when both conditions apply:
- You expect to owe at least $1,000 after subtracting withholding and refundable credits from your expected federal tax for the year.
- Your withholding and refundable credits will be less than the smaller of 90% of your expected 2026 tax or 100% of your 2025 tax. For taxpayers above the applicable adjusted-gross-income threshold, the prior-year comparison is generally 110% instead of 100%.
The $1,000 amount is an expected balance after withholding and refundable credits—not your total tax before those items. A person with a large tax bill can still avoid estimated payments if enough tax is withheld during the year.
How the prior-year safe harbor works
The prior-year benchmark is generally the tax shown on your previous year’s return. The higher-income rule generally applies when prior-year adjusted gross income exceeded $150,000, or $75,000 for a married taxpayer filing separately. In that situation, the usual prior-year target is 110% of the prior-year tax. Use the current Form 1040-ES instructions for the exact year-specific definition and exceptions.
Recommended Free Tools
Meeting a safe harbor generally protects you from an underpayment penalty, even if your final return shows a balance due. It does not eliminate the tax itself; any remaining tax is still payable by the annual return deadline.
Situations with different rules
The 90%, 100%, and 110% tests are general rules. The IRS identifies special provisions for farmers and fishers, fiscal-year taxpayers, nonresident aliens, certain household employers, and other circumstances. If one of these describes you, follow the instructions that apply to that category instead of assuming the regular four-payment schedule works.
Calculate your 2026 installments with Form 1040-ES
The 2026 Form 1040-ES package contains the individual estimated-tax worksheet, payment vouchers, and instructions. It is the starting point for estimating your full-year tax and determining whether an installment is required.

Gather the figures the worksheet needs
- Expected wages, self-employment income, freelance or contract income, rental income, interest, dividends, gains, and other 2026 income.
- Expected adjustments, deductions, and credits.
- Federal income tax already withheld from pay, pensions, or other payments.
- Refundable credits you expect to claim.
- Self-employment tax and other taxes that belong in the estimated-tax calculation.
- Your prior-year tax information for the safe-harbor comparison.
Use reasonable year-end estimates rather than simply copying last year’s income. A new contract, sale of investments, change in filing status, large deduction, or change in withholding can materially alter the result.

- Project your 2026 income and adjustments.
- Calculate expected taxable income and the associated income tax under the worksheet’s instructions.
- Add self-employment tax and other applicable taxes.
- Subtract expected withholding and refundable credits.
- Compare the remaining amount with the $1,000 threshold and the 90%, 100%, or 110% payment benchmarks.
- Use the worksheet’s annual amount to determine the required installments and transfer the amounts to the vouchers or your electronic payment plan.
Do not assume the answer is always one-quarter of a single guessed annual amount. Equal installments are common when income is steady, but the timing of income and the worksheet’s annualized-income method can change the required payment pattern.
Illustrative calculation
Suppose a taxpayer estimates total 2026 federal tax of $12,000, expects $5,000 of withholding, and has no refundable credits. The expected balance is $7,000, so the $1,000 test is met. The taxpayer would then compare the amount paid through withholding and estimates with the applicable current-year and prior-year safe-harbor percentages. This example demonstrates the process only; your worksheet result depends on your income, deductions, credits, filing status, and prior-year tax.
When quarterly estimated payments are due in 2026
For a taxpayer using the calendar year, the ordinary 2026 estimated-tax dates are:
| Installment period | Due date | What the payment covers |
|---|---|---|
| First | April 15, 2026 | Income generally received January 1 through March 31 |
| Second | June 15, 2026 | Income generally received April 1 through May 31 |
| Third | September 15, 2026 | Income generally received June 1 through August 31 |
| Fourth | January 15, 2027 | Income generally received September 1 through December 31 |
Each date applies to its own installment. The fourth payment is in January 2027 even though it belongs to tax year 2026. If a due date falls on a Saturday, Sunday, or legal holiday, the deadline moves to the next day that is not a Saturday, Sunday, or legal holiday.
Fiscal-year taxpayers do not use these calendar-year dates. Farmers and fishers may have a different payment pattern, and special rules can apply when most income arrives late in the year.
How to pay 1040-ES online
You can use several IRS-supported channels. Choose the method that matches your need for scheduling, speed, cost, and recordkeeping.
| Method | Best use | Cost and record notes |
|---|---|---|
| IRS Direct Pay | One-time bank transfer from a checking or savings account | No IRS service fee; save the confirmation number. The payment may take time to appear in your IRS account. |
| IRS Online Account | Payment plus a view of payment history and other account information | Registration is required; review the account after the payment processes. |
| EFTPS | People who want to schedule estimated payments at intervals | Confirm current enrollment and scheduling requirements before relying on it. |
| Card or digital wallet | Electronic payment when a card or wallet is preferred | Third-party processor fees apply; check the current IRS-linked processor terms. |
| Electronic funds withdrawal | Payment arranged as part of electronic filing | Confirm the debit date, bank details, and tax year in the filing workflow. |
| Mail with Form 1040-ES | Paper payment using a voucher | Use the current voucher and mailing address; retain proof of mailing and payment. |
Pay with IRS Direct Pay
Direct Pay moves money directly from your bank account without an IRS service fee. IRS instructions describe it as a one-payment-at-a-time service.
- Open the IRS Direct Pay service and select the payment type for an estimated tax payment.
- Select the tax year, generally 2026 for these installments, and the applicable reason for payment.
- Complete the identity-verification questions using information from a prior federal tax return.
- Enter your checking or savings account and routing details.
- Review the tax year, payment amount, bank information, and debit date.
- Submit the payment and save or print the confirmation number.
A confirmation means the request was submitted; it is not by itself proof that the bank debit cleared. Check your bank account and IRS payment history, especially if the transaction does not appear promptly.

Reconcile the account history with your own records rather than assuming a pending transaction has posted.
Use a card or digital wallet
The IRS lists authorized processors for card and digital-wallet payments. The processor—not the IRS—charges the convenience fee. Review the current fee and service limits before submitting, and keep both the IRS payment confirmation and the processor receipt.
Mail a Form 1040-ES voucher
If you pay by check or money order, complete the voucher for the correct installment and tax year, make the payment payable as instructed, and use the mailing address in the current 2026 Form 1040-ES instructions. Do not send cash. Keep a copy of the voucher, the payment instrument details, and proof of timely mailing.

What if your income is uneven?
Income from a business, investments, rentals, or a one-time transaction may arrive unevenly. Four equal payments can then leave you overpaying early or underpaying during a high-income period.

Form 2210 and its Schedule AI are used to show the timing and calculate annualized installments. This method requires detailed records by period and is more involved than dividing an annual estimate by four.
When to revisit your estimate
Recalculate after a substantial change in income, deductions, credits, withholding, filing status, or other taxes. Examples include starting or stopping self-employment, a large stock sale, a major rental change, a bonus, a new job with different withholding, or a significant business expense.
If the revised calculation increases the required amount, make up the difference as soon as practical. If it lowers the amount, later installments may be reduced, subject to the worksheet and any annualized-income calculation.

The IRS can assess an underpayment penalty when required tax was not paid on time during the year. This can happen even if your annual return produces a refund, because the penalty generally considers each installment’s required amount and the period it remained unpaid.
Do these 3 things before closing this tab:
1Scan for outdated or missing drivers - takes under a minute2Clear out junk files and repair common Windows errors3Fix the driver behind crashes, sound loss and screen glitchesThe calculation depends on the underpaid amount, how long it was outstanding, and the IRS interest rate published for the relevant quarter.

Common penalty protections
The IRS penalty guidance describes avoiding the penalty when the return shows less than $1,000 due, or when payments meet at least 90% of current-year tax or 100% of prior-year tax, with the higher-income substitution where applicable. These are year-specific rules; use the current Form 1040-ES and Form 2210 instructions when determining whether an exception or waiver applies.
Special exceptions can apply to farmers, fishers, people whose income arrives unevenly, taxpayers who became disabled or retired, and other situations identified in the instructions. Do not assume that paying the full annual balance with the tax return automatically erases an earlier installment penalty.
If you realize a payment was late
- Make the missed or short payment as soon as possible rather than waiting for the next scheduled date.
- Recalculate the remaining installments using current income and withholding information.
- Keep the payment confirmation and bank record.
- When filing, review Form 2210 and its instructions to determine whether the penalty is calculated, excluded, or eligible for an exception.
Recordkeeping and reporting on your tax return
Keep a year-to-date ledger showing the date, amount, tax year, payment channel, confirmation number, and bank or processor reference. Save copies of mailed vouchers and proof of mailing. Your records should distinguish federal estimated payments from federal withholding and from state payments.
When you file your individual return, estimated payments are reported on Form 1040, line 26, according to the IRS estimated-tax FAQ. Compare that line with your confirmations and IRS account history. If the IRS record differs from your ledger, investigate before assuming a payment was credited to the correct year.
A practical 2026 checklist
- Read the 2026 Form 1040-ES instructions and identify whether a special rule applies to you.
- Estimate income, deductions, credits, withholding, self-employment tax, and other applicable taxes.
- Apply the $1,000 expected-balance test and the 90%, 100%, or 110% payment benchmarks.
- Mark April 15, June 15, September 15, 2026, and January 15, 2027 on your calendar.
- Choose a payment channel and verify the tax year before submitting.
- Recalculate after a major income or withholding change.
- Use annualized installments and Form 2210 Schedule AI when income timing makes equal payments inappropriate.
- Save every confirmation and reconcile it with your IRS account and bank records.
- Check separate state and local requirements; federal payments do not satisfy them.
Questions taxpayers commonly ask
Can I pay estimated tax in one payment instead of four?
You can generally pay more than the minimum installment early, but the required-payment and penalty rules still measure whether enough tax was paid by each applicable date. Follow the Form 1040-ES and Form 2210 instructions rather than assuming one early payment automatically resolves every later-period calculation.
Does estimated tax include self-employment tax?
Yes. The estimated-tax calculation can include both income tax and self-employment tax. Include the amounts called for by the current Form 1040-ES worksheet.
Will an estimated payment automatically appear on my return?
No. Keep your own records and report the payments correctly on Form 1040, line 26. Verify the IRS account history and resolve discrepancies.
Are these dates the same for state taxes?
No. This schedule is for federal individual estimated tax. State and local agencies set their own rules, forms, thresholds, and deadlines.
